From the data sheet and product page, it looks like the camera is exactly what it is intend to be and nothing more. A low resolution security camera and not for any inspection purposes. You only get access to a upscaled video stream that gets compressed for streaming, no hint of raw data and not a word about radiometric access.
You also won't get any wavelength information out of a radiometric camera meant for inspection or research, you get a temperature for each pixel based on some calculations form the sensor response and it's own temperature etc. LWIR is a very broad spectrum because radiation gets lower in power the longer the wavelength. If you are interested in spectroscopy, or even (far)infrared spectroscope - you will need to spend a lot more money. Even low pass, high pass(cut-) filters for the LWIR spectrum cost a few hundred.
Good luck. It isn't unheard of badly designed firmware in network cameras that allow you to hack them(more like a network intrusion and less of a liberation of hidden features, but look into that for a chance).
